Further evidence suggests that mutations are indeed present at detectable frequencies in the differentiated somatic tissues of both seed and vegetatively propagated plants.

Ideotype Research and Plant Breeding,nd it is encouraging that yield gains have been sizeable and sustained (Duvick, 1977; Austin et al., 1980; Riggs et al., 1981; Wych and Rasmusson, 1983; Wych and Stuthman, 1983). We should take satisfaction in and applaud conventional plant breeding.

Book 1984s of embryo culture, ovule culture, and in~ pollination and fertilization represent an extension of the normal sexual hybridization process. Successes recorded in obtaining hybrids stem largely from circumventing prezygotic or postzygotic hybridization barriers. Numerous recent successful hybridizat
